Application filed May 28, 1915. Serial No. 31,077.

To all whom it may concern Be it known that I, WILLIAM STUEBING, United States, residing at the city of Cincinnati, in the county" of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combined Slitting and Collecting Machines, of which the following is a specification.

The object of means forsupporting and cutting a sheet into strips and then'collecting said out strips and delivering them to a given point.

The salient features of the invention consist in means for properly sup'portingthe sheet tobe cut, feeding the sheet under cutters or slitters, means for engaging and guiding the sheet and strips during the opera tion of the cutting mechanism, means for releasing the engaging mechanism when the strips have been cut and mechanism for collecting the cut strips and delivering them to a given point. The sheets to be cut may be fed to the cutters or slitters by hand or any other means or the machine may be connected directly to a printing press or machine which produces the sheets to be cut and fed by some preferred mechanism auto matically to the slitters orcutters.

The various features of my invention and their advantages will readily become apparent from the followingspecification.

In the accompanying drawing forming,

part of this specification: Figure 1, is a side elevation of my 1nvent1on, F1g. 2, 1s a side elevation of Fig. 1 attached to a printingpress, Fig. 3, is a plan view of Fig. 1, Fig. 4, is an end view of the machine, Fig. 5, is an enlarged sectional view, taken on the line 5-5 of Fig. 3, Fig. 6, is an enlarged sectional view taken on the line 6-6 of Fig. 3,

Fig. 7, is a plan view of Fig. 1 showing sheet of paper passing through the slitters,

and Fig. 8, is an enlarged section on line- 88 of Fig. 7

The frame of themachine 'is composed of side pieces 1 and is tied together by the cross-pieces 2 in any of the usual ways of making the frame work'for machines of this character.

The machine is-driven the driving shaft 3, journaled in the frame in bearings 4, in any preferred manner. This shaft 3 carries the bevel gear 5 meshing with gear 6 on a shaft 7 This shaft 7 is journaled in a housing 8. On a shaft 9, I carry a bevel gear 10 operating through bevel gear 11 on my invention is to provide 'ters the grippers 'son of the rocking of the rock shaft which the machine; if I wish to said shaft 7. The shaft 9 is journaled in bearings 12 and carries at its extremity the crank 13.

Power is transmitted to the shaft 3 by any suitable means, not shown in Fig. 1, but applied to' a printing press in Fig. 2, this shaft thus revolves shaft 7 and also shaft 9. Any mechanism maybe used'toloperate the machine. i

I provide a feed board or a series of strips 14 upon which the sheet or card to be cut into strips is placed in order to be fed under the slitters or cutting devices which cut the sheet into strips.

Two shafts carry the slitters or cutters. The sheet when it has been fed to the slitters, just before the slitting operation starts is grasped by grippers which pull it through the slitters, guiding the strips and preventing buckling by holding them taut. One set of the fingers which form the grippers is attached to a rock shaftso that they will be rockeddown to meet fingers on a bar below, the sheet tobe slit being held be tween the grippers formed by these fingers. When the sheet has passed through the slitlet go their hold by reacarrier the upper fingers. When the strips have passed through the slitters and are cut to theirfu'll extent, the said strips rest upon a series of tapes or mechanism which carries them, all collected, to a point at side of mach1ne;'th'e latter mechanism operatmg 1n a direction at a right angle to the slitting or cutting mechanism.

I may 'attach th e. machine to a printing press or to a'machine which forms the sheets and automatically feed them off of said machine to the feed board which takes the sheets to the slitters to be cut.

I may cut the sheet into as many strips as desired, in the present instance I show the sheet being cut into eleven strips, see Fig. 7, so I use eleven grippers so that each of the eleven strips will be properly taken through cut, say for example, eight strips I would use eight grip- .pers, and if I wished to cut thirty strips I would use thirty grippers.

The grippers are timed to grasp the sheet just before it is to'be slitted and are timed to release their hold on the cut strips, so that they can be collected or gathered together and delivered at a given point at the side of the machine.

On each side of the machine on the frame 1, I place suitable housings 15. In these housings I mount two shafts 17 carrying the slitters 16 and the spur gears 18 and 19' which drive the shafts 17 carrying said slitters 16. This operation is done as follows: On the upper shaft 17 I mount a gear 20, which meshes into a rack 21, mounted on a traveling carriage 22 on each side of machine, connected by the link 23 to rocker arm 24, and fulcrumed at 25 and at point 26 connected to a long link 27 while at its other end it is fastened to a crank 28 mounted on the shaft 7. The top shaft 17 is the driving power and its spur gear 18 meshes with spur gear 19 on the lower shaft 17. The traveling carriage 22 travels forward and backward on the upper part or edge of racks 29, on the rollers 30 when the rocker shaft 24 is rocked forward and backward and at the same time transmits power through rack 21 to the shafts 17 17 The carriage 22 carries a shaft 31, extending across the machine and at the outer extremity of this shaft 31, I place the gears 32 which mesh in the teeth of rack 29. A shaft 33 having bearings in carriages 22 and passing entirely across the machine carries the upper gripper fingers 34. To the carriages 22 I also connect a bar 35 passing across the machine, to which are attached the lower gripper fingers 36. ,In orderto operate the shaft 33 I provide the lever 37, which, at one side of the machine is attached to the shaft 33 which carries the upper gripper fingers 34; the shaft 33 is a rock shaft and is operated through the agency of the lever 37, on which is carried roller 38. On the upper shaft 17 at its outer extremity I also provide a cam faced lever 39 to which motion is imparted through link.40 and bell crank41 attached to the frame of the machine and operating on cam 42 having nose 43, a roller 44 on the bell crank 41 operating over the face of cam 42, thus imparting a rocking motion to said cam faced lever 39 on upper shaft 17, thus acting on the lever 37 and rocking the shaft 33 and consequently opening and closing the gripper fingers 34 away from and toward the gripper fingers 36 on the bar 35, thus gripping the sheet 96 and holding onto the strips 95 as they are being cut and releasing their hold when the entire strip has been out, see particularly Figs. 7 and 8. The housings 15 also carry through bearings 45, a shaft 46, carrying the tapes 14 on the roller 47, said shaft 48 is driven from the mechanism of a printing press 100, as shown at point 48, see Fig. 2. If the machine is not attached to a printing press, but is fed separately by hand-or some other way, the tapes can be made stationary and act as a feed board. In the housings 15, I also carry the rocker shaft 49, provided with the stop fingers 50, which are permanently fastened to said shaft 49, a rocking motion is developed through by the the action of the cam 42, roller 44, bell crank 41 and the link 40, same as is imparted to cam lever 39.

At the point 51, on the link 40 I carry the arm 52, fastened at its outer extremity to shaft 49. The rocking motion of shaft 49 also rocks the fingers 50 dropping the fingers below the line of the sheet 90 to be cut or slitted, thus allowing the sheet 90 to pass over the fingers. If attached to the printing press, then we use the foregoing mechanism for stopping the sheets as they come off of the press; this mechanism is not operated when the sheets are fed by hand or in some analogous way.

In the housings 15, I carry a rock shaft 53, and fastened to the shaft are arms 54 connected at point 55 to uprights 56 upon which uprights are connected wooden sticks 57, spaced in between the tapes 14 and these sticks just set below the surface of the tapes. The rock shaft 53 is operated through the arm 58 fastened at opposite extremity of shaft53 and at the point 59 is connected to the link 60, which link 60 is pivoted on a bell crank 61 (see Fig. 4), and operating on 69, which is journaled at bearings 7 O on the arm 66. Fastened to the gear 68 is a ratchet wheel 71. On shaft 69, I connect an arm 72 carrying a ratchet pawl 73, at point 74. This pawl 73 is so placed as to engage in the teeth of the ratchet pawl 71, and the ratchet pawl and gear 68 are independent of the shaft 69. At the outer end of shaft 69, I key the gear 75. Fulcrumed on the shaft 69, I carry the double sliding bearing 76 which carries the rack 77 meshing into gear 75.

The rack 77 is connected atthe point 7 8 arm 79 fastened at the outer extremity of shaft 9, thus it will be seen that power is transmitted through shaft 9 to the arm 79 and rack 77 which is in mesh with gear 75, which operates the shaft 69, the shaft in turn operating the. arm 72, transmitting motion to the ratchet wheel 71 and it, in turn, revolves gear 68, driving the gear 67 which gives motion to the roller 64, and the tapes 80 passing over the roller 64, said tapes carrying the slitted strips over to a position at the side of the machine to a box 81.

When a printing press is used the sheet is conveyed by the strips 82 to the tapes 14 on the slitter. The sheet to be slitted is fed onto the tapes 14 and passes over the sticks 57 up to the stop fingers 50, here the sheet rests until gripper fingers 34 and 36 grasp said sheet. Any kind of mechanism may be used to take the sheets 90 from the printing press 100.

From the above description it Will be seen that my improved combined slitting and collecting machine, constructed according to my invention, is of an extremely simple and inexpensive nature, and is especially Well adapted for the purposes for Which it is designed, and it Will also be obvious from the above description, that the combined slitting and collecting machine is capable of considerable modification without material departure from the principle and spirit of the invention, and for this reason I do not Wish to be understood as limiting myself to the precise form and arrangement of the several parts of the machine as herein set forth, in carrying out my invention in practice.
